Automatic Weather Station All the data for the weather station can be found on: https://cf.regione.vda.it/portale_dati.php Termometro - Thermometer for measuring temperature, Igrometro (%) - Hydrometer for measuring humidity, Solarmetro (min) - Pyranometer for measuring solar radiation, Radiazione totale (watt/m2), Pluviometro (mm) - Rain gauge for measuring precipitation, Nivometro (cm) - Snow gauge for measuring snow depth,. Barometro di prec. (hPa) - Barometer for measuring atmospheric pressure, Rosa dei venti - Wind vane for measuring wind direction,

Nature guide explanation

Davide D’acunto- New forest, birch (betulle)- ash tree (frassino) - burns easily, seeds spread easily. winged seeds (semi alati) transported by the wind Lolita - how seeds are transported. (Bardana - Burdock) Seeds attach to the animals. How to detect animals - An animal track is an imprint left behind in the soil, snow or mud. - imprints (impronti), excrement , Bark (corteccia) damage to the bark of the trees - Bark is a food source for many animals.

How can a hare get its nutrients?

Eats plant buds (germogli). Can reach the buds because plants are squashed by the snow. Eats it’s own excrement to get all the nutrients. A hare can produce 400 droppings (poo balls) a day.

Birch Tree .

The wood is a light, strong and durable and used for making furniture and buildings. Also good for burning as it produces a good heat. The bark can be removed easily and is strong and water- resistant. It can be easily cut, bent and sown for a variety of uses.

Deer and Goats

Deer (cervo), Roe deer (capriolo) They drow and shed (lose) antlers annually. Males typically begin growing a new set of antlers in late spring. Antler growth is regulated by hormones, which a controlled by photoperiod (day length). Chamois (camoscio) and Ibex (stambecco) do not lose their horns. They carry them for their lifetime. Chamois - goat-antelope with small hooked horns. Alpine Ibex (bouquetin) is a type of wild goat with large curved horns (they are protected and cannot be hunted)

Larch - larice

Used for furniture, for burning, to make roofs of houses, bark burns slowly and so plant resistant to fire. Water resistant Big roots to find water and keep the rocks and earth together. Prevents landslides (frana). Grows well in VDA which is very dry. Larch needles - soft lots growing from one point.

Spruce / Christmas Tree- Abete rosso

Grows near larch/Grows quickly / Roots small / evergreen Not good for building because of knots in the wood where branches fall off / single flat needles

Wild boar and foxes excrement

Excrement can help us understand all the wildlife living in a certain area. Herbivores - round shaped poos Carnivores - sausage shaped poos

Animal Teeth

Difference between herbivores, omnivores and carnivores. Wild boar and fox.

Identifying trees in the the forest.

Larch (larice) lighter and Spruce (abete rosso) - darker green. In autumn larch turns orange. Observing the strategic place Courmayeur is built. Protected from avalanches and landslides by the forest.
